To aZZ whom 2'25 may concern:

Be it known that we, MARTIN PLOOI-IER and ELIJAH A. Scorr, citizens of the United States, residing at St. Louis, State of lVllS- souri, have invented certain new and useful Improvements in Sanitary Cuspidors, of which the following is a full, clear, and exact description; reference being had to the accompanying drawings, forming apart hereof.

Our invention has relation to improvements in sanitary cuspidors; and 1t consists in the novel features of COIlSlIIUCtlOIl more fully set forth in the specification and pointed out in the claims. p

In the drawings, Figure 1 is a combined side elevation and vertical middle section of the cuspidor having our improvement applied thereto; Fig. 2 is a vertical section on the line 22.of Fig. 1; and Fig. 3 isa top plan of the ouspidor with one lalf of the cover removed. 1' y i The present is an improvement on the construction of cuspidor covered by U S Patent 1,047,287 issued to Martin Plocher under date of December 17, 1912; and has for its object. to provide means which will in a large measure segregate, the injurious and disease-breeding germs from the-flush water thereby rendering the cuspidor emi nently sanitary; to simplify tor-a degree the operating parts of the flushing apparatus; to provide means for preventingthe splashing' of the water on the floor or surface supporting the cuspidor; and to construct a cuspidor which shallin a large measure be attractive and which shall possess further and other advantages better apparent from a detailed description of the invention which is as follows. i

Referring to the drawings; 1 represents a vessel or water container provided with a removable conical hood or cover 2 having a central discharge opening 0, an annular perforated spray-pipe 3 being positioned beneath an annular deflector or deflecting fian 'e 4 disposed aboutthe outer edge of the hood. A pairof hollow nipples 5 depend from said spra, -pip'e inside the vessel 1 and project through the walls of the hood, the said nipples being located diametrically opposite one another. Located within the container adjacent to the wall thereof is a pump-cylinder 6 from the lower portion of which lead pipes 7, 7, entering the. nipples 5 and thus discharging into the spray-pipe 3.

and being guided in its From the cylinder 6 leads a third pipe 7' disposed along the axis of the container and projecting through the discharge or drain opening 0 of the hood, to a point above said hood. The pipe 7 terminates in a deflecting head 8 beneath which the pipe is perforated to flush the spittle and other foreign matter not effectively washed down by the jets from the spray pipe 3. To the perforated spring controlled valved piston 9 is secured a piston-rod or stem 10 provided with an offset or shoulder a at an intermediate point, the portion of the stem above said ofl set operating in close proximity to the inner face ofthe wall of the container,

reciprocations between the sidesorears ll, 11, of a bent racket secured to the container wall, there being journaled between the ears an antiriction roller 12 whichnot only serves to form an additional, guide for the stem but serves to limit the stem in its upward stroke by coming in contact with the offset.

The bases of thepipes 7, 7, 7, are disposedclose to the bottomof the container, said basal portionsserving to retain in proper position within the container and close to thepunip-cylinder, a strainer plate 13, said plate being provided with bottom notches 71, which span the basal portions of the aforesaid pipes, the opposite vertical edges of the plate engaging the inner walls of the container. The upper portion of the plate may be suitably bent to slightly over hang the pump-cylinder and also to serve as a finger hold when there is occasion to pull out the plate and clean the same The perforations 03 in said strainer are disposed symmetrically about a horizontal line passing through the center of the plate the latter placed as described dividing the interior" of the container into two intercommunicating compartments. Into the larger compartment C the spittle and solid matter are ischarged from the hood or vcover 2, the contents of this compartment being filtered by the strainer, the clear water or filtrate entering the adjacentor partment C. The hood: is notched at a convenient point along its outer edge (the spray pipe 3 terminating on each side of the notch and being closed at its ends) to permit the piston-rod or stem 10 to play freely through it. I

Pivoted to suitable brackets 14, 14, on the bottom of the hood and on each side of the smaller com- 7 drops from under the arms 15, 15 allowing center of the opening 0 thereof, are the hinge-rods 15 of a pair ofgates 16, 16, which normally close across said opening 0 of the hood, the said rods terminating opposite the piston-stem 10 in inwardly deflected parallel arms 15, 15, adapted to ride over and rest on a pin, or arm, or equivalent member 17 projecting from the piston-stem. The free ends of the arms 15 are bent upward, the convex curvatures of such bent ends preventing binding of the parts and insuring an easy play of the arms over the member 17 under all conditions and for any position of the pump-piston. The upper end of the stem 10 terminates in a lug or finger-hold 10. 7

Parts not alluded to but shown in the drawings, are well known in the art and require no description in the present connection.

' The operation is as follows :-With a depression of the stem 10 (which may be done by the water (which is maintained at the level a: Fig. 1) is expelled from the cylinder 6 (into which it finds access through the perforated piston) through the pipes 7, 7, 7 and spray coil 3, the annular deflector 4 insuring a positive projection of the sprays from the pipe 3 onto the hood and preventing any splashing of the water on the floor. With the depression of the piston (due to a depression of the stem 10) the pin or arm 17 the gates 16, 16, to drop (see dotted position Fig. 2) and allowing the spittle and wash water to discharge directlyv into the compartment C. When the stem is released the spring S which controls the piston will raise:

the latter, thus lifting the gates (the pin 17 now raising the arms 15, 15, and rocking the hinge-rods 15 in the opposite direction) which jointly close across the opening 0. With an upward movement of the piston fresh water enters the pump cylinder through the perforations ofthe piston to supply the spray water for the next downward stroke. Only clean water may enter the pump-cylinder, such water being supplied to the compartment C, in which the pump is located, by the action of the strainer 13 the perforations in which are of proper mesh to exclude the majority of solid particles from the compartment C, and a very large percentage of injurious germs. It follows therefore thatithe flushing is done with the water which is comparatively clean.

- Of course, from time to time the cuspidor is thoroughly scalded and washed, which should be done under all circumstances.

An inspection of Fig. 1 of the drawings shows that the upper deflected or bent edge ofthe plate 13 is bowed sufficiently toward the compartment C so as to cause all the drainage from the hood 2 to discharge into hand seizing the finger-hold 10) claim is:

the compartment C, the bowed portion catching any material which drips from the a hood 2 and directing it into said compartmentC. As to the strainer perforations (Z it will be noted that they are distributed over a portion only of the plate 13, the upper and lower portions of the plate-being left imperforate. The upper imperforate portion thus excludes from the compartment C the injuriousgerms which may be floating near the surface of the liquid in the compartment C (the level of the liquid being indicated by the dotted line Z20), while the lower imperforate portion of the plate excludes from said compartment the germs congregated in the bottom layers of the liquid in the compartmentlO, We have found by actual test that the middle portionsof the liquid in the compartment C, or thoseopposite the perforations-d carry very few germs, so

through said perforations into the compartment C in which the pump islocated will be comparatively free from germs, and the flush water sprays be reasonably clean. To prevent any dirty liquid finding its way into the compartment G, from the compartment C, through the notches h in the bottom of the plate 13, we close said'notches by means of the plates or panels 'w soldered or otherwise secured to the bottoms of the pipes 7 7 against which panels the filter plate 13 is caused to bear.-

Having described our invention,- what we 1, In a cuspidor, a suitable container, a cover, therefor provided with a discharge opening, a piston pump, pipes'leading from V the pump-cylinder having basal portions '7 contiguous to the container bottom and vertical portions discharging ontothe cover, and thereby flushing the latter, a detachable strainer disposed on one side'of the pumpcylinder and dividing the container into two compartments in one of which the pump is located,'the bottomof the strainer being notched to pass over the basal portions of the pipes aforesaid, and the upper I edge of the strainer being provided with a bent port-ion overhanging the pump-cylinder, the discharges from the cover-being received in the compartment contiguou's to that in whichthepump is located, the parts i operating substantially as, and for the purpose set forth.

2. In a cuspidor, a suitablecontainer, a

piston-pump in said container, a'piston-rod leading from the piston and disposed along the inner face of the 'wall of the container, a cover draining the spittle into the. container and provided with a central opening, a hinged gate carried by the cover'and closing across the opening aforesaid for a raised position of the pistonyandmeans. interposed between the-pistOn-md and gate 7 for supporting the gate in its closed p0- sition, the gate dropping to open position with a depression of the piston.
